Heat Pump Leaking Water Outside Unit! How to Fix it?

Water leaking from your heat pump unit is not only unsightly, but it can also lead to serious damage to your home. If you think your heat pump may be leaking water, it’s important to take action right away. By troubleshooting the issue and taking steps to fix it, you can prevent further damage and keep your home safe.

Are you noticing water around your heat pump’s outdoor unit? If so, there’s a good chance your heat pump is leaking and needs to be repaired. Heat pumps work by moving heat from one place to another.

In the winter, they move heat from the outdoors into your home. In the summer, they do the reverse and move heat from your home to the outdoors. Because heat pumps rely on this transfer of heat, they have two units: an indoor unit and an outdoor unit.

The outdoor unit contains a refrigerant that helps to cool or warm your home, depending on the season. If your outdoor unit is leaking water, it could be because of a number of different issues. One possibility is that the condensate drain line is clogged or frozen.

This line drains away any moisture that condenses on the coils inside the outdoor unit. Another possibility is that there’s a problem with the evaporator coil inside the outdoor unit. This coil can become frozen in certain conditions, which will cause water to leak out of the unit.

If you’re seeing water around your heat pump’s outdoor unit, it’s important to have a professional take a look at it as soon as possible.

Why is My Outdoor Unit Leaking Water?

It’s not uncommon for your outdoor unit to leak water, especially during the warmer months. There are several reasons why this may be happening, and we’ve compiled a comprehensive guide to help you troubleshoot the issue.

One of the most common reasons for an outdoor unit to leak water is due to a clogged drain line. The drain line is responsible for carrying away any condensation that forms on your unit, and if it becomes clogged, that water will have nowhere to go but out the sides of your unit. To clean your drain line, simply remove it from the outdoor unit and flush it out with a garden hose.

Another common reason for an outdoor unit to leak water is because the evaporator coils are frozen. This is most likely to happen during the winter months when the temperature outside is very cold. If your coils are frozen, it’s important to thaw them out as soon as possible to prevent any further damage to your unit. The best way to thaw out your coils is to turn off your unit and let it sit in the sun for a few hours.

If your outdoor unit is still leaking water after you’ve checked the drain line and evaporator coils, it’s possible that there is a problem with the compressor. The compressor is responsible for circulating refrigerant through your unit, and if it’s not working properly, it can cause your unit to leak water. If you suspect that the compressor is the problem, it’s best to call a professional to take a look at it.

Ultimately, if your outdoor unit is leaking water, it’s important to investigate the issue as soon as possible. Ignoring the problem could lead to further damage to your unit, which could end up costing you a lot of money to repair.

Why is My Mitsubishi Heat Pump Leaking Water?

One of the most common issues that homeowners face with their heat pumps is water leaks. If you’ve noticed water pooling around your heat pump, it’s important to take action immediately to avoid further damage. Here are some potential causes of a leaking heat pump and what you can do to fix the problem.

The most common cause of a leaking heat pump is simply condensation. As the warm air from your home hits the cold coils of the heat pump, moisture can build up and eventually drip down onto the floor. While this type of leak is usually not harmful, it can be quite annoying.

The good news is that there are a few easy ways to combat condensation buildup on your heat pump.

Before all, make sure that your heat pump is properly insulated. This will help keep the warm air from escaping, which will in turn reduce condensation formation.

You can also try placing a dehumidifier near the heat pump to help absorb excess moisture in the air. Be sure to keep an eye on your humidity levels inside your home; if they’re too high, it can lead to excessive condensation formation on your heat pump (and other surfaces). If you have ruled out condensation as the cause of your leak, then it’s possible that there is an issue with one of the components inside your unit itself.

One possibility is that the evaporator coil has developed a leak; this component holds refrigerant which can be damaging if leaked into your home.

Heat Pump Leaking Water Outside Unit in Summer

If you find that your heat pump is leaking water outside during the summer months, there are a few things that could be causing the issue. First, check to see if the unit is properly leveled. If it’s not, then water can collect in the condensate pan and eventually overflow.

You can adjust the legs of the unit until it’s level again. Another possibility is that your heat pump isn’t getting enough airflow. The condenser needs adequate airflow to function properly.

If there’s something blocking the airflow (like leaves or debris), then that could cause water to leak from the unit. Make sure there’s nothing obstructing the airflow around your heat pump. Lastly, it’s possible that your heat pump simply needs to be cleaned.

Over time, dirt and dust can build up on the coils and cause them to become less efficient. This can lead to water leakage as well. Cleaning the coils regularly will help prevent this from happening.

Heat Pump Leaking Water Outside Unit in Winter

When your heat pump leaks water outside the unit in winter, it’s a sign that the system is not working properly. There are several possible causes for this problem, and it’s important to diagnose the issue so that you can get your heat pump back up and running as soon as possible. One of the most common causes of a heat pump leaking water is a frozen evaporator coil.

When this happens, the ice buildup prevents proper airflow through the coil, which causes condensation to form on the outside of the coil. This condensation can then freeze, forming an ice blockage that prevents the proper operation of the heat pump. If you notice that your heat pump is leaking water and you suspect a frozen evaporator coil, there are a few things you can do to try to thaw out the coil.

Turn off the power to the heat pump at the breaker box. Use a hair dryer or space heater to warm up the area around the coil (be careful not to overheat anything). You can also try using a garden hose to thaw out the ice blockage; just be sure to direct the stream of water away from any electrical components.

Once you’ve thawed out the evaporator coil, restart your heat pump and see if it’s still leaking water. If so, then you’ll need to call a professional for help diagnosing and repairing whatever other issues may be causing your problem.

Heat Pump Condensation

If you have a heat pump, you may have noticed that it produces water as it runs. This is normal and happens as the system pulls warmth from the air outside and uses it to heat your home. The water comes from condensation that forms on the coils of the outdoor unit.

As the temperature of the coils drops, moisture in the air around them condenses on the coils. This process is similar to what happens when you see water droplets form on a cold can of soda. The difference is that with a heat pump, this moisture is collected and drained away so it doesn’t cause any problems.

If you live in an area with high humidity, you may notice more water being produced by your heat pump. This is because there is more moisture in the air for the system to collect. In most cases, this isn’t a problem and your heat pump will continue to work properly.

However, if too much water is being produced, it can cause issues with drainage and lead to leaks or other damage. If you think your heat pump is producing too much water, there are a few things you can do to help reduce the amount of condensation it produces:

  • Make sure your outdoor unit has adequate ventilation so air can circulate around it freely.
  • Reduce humidity inside your home by using a dehumidifier or opening windows on dry days.
  • Clean or replace your filter regularly to ensure proper airflow through the system.

How Much Condensate Does a Heat Pump Produce?

One of the most frequently asked questions about heat pumps is, “How much condensate does a heat pump produce?” The answer to this question can vary depending on a number of factors, but in general, most heat pumps will produce between 10-15 liters per hour. There are a few things that can affect the amount of condensate produced by a heat pump, including the climate, the size of the unit, and the efficiency of the unit.

If you live in an area with high humidity, you may find that your heat pump produces more condensate than usual. This is because the air is already saturated with moisture, so the heat pump has to work harder to remove moisture from the air.

Similarly, if you live in an area with very cold winters, your heat pump may also produce more condensate than usual as it works to keep your home warm. The size of your heat pump also plays a role in how much condensate it produces. Larger units will typically produce more condensate than smaller units simply because they have more coils that come into contact with moist air.

Newer and more efficient models of heat pumps tend to produce less condensate than older models because they are better at removing moisture from the air. So how much should you expect your particular heat pump to produce?


A heat pump leaking water outside the unit is not a good sign. This means that the refrigerant inside the heat pump is not being cooled properly and is causing the water to leak out. If you see this happening, you should call a technician to come and take a look at it as soon as possible.
